I am getting ready to buy a 1993 325is and here lately I have been noticing that there are E36 and E46 and all this other technical termes. Can anyone please tell me what that means and which one I more than likely have in my 1993 325is.

the 1993 E36 3series which is what you have uses an in line six cylinder engine with a twin cam ie 24 valves. In september 1993 BMW introdeuced vanos intoo the engine which varies the valve timing giving much betteer low down torque than the non variable valve model. If possible find out under the bonnet or hood as you guys in the states call it for the build date. Models built september 1993 onward have the variable valve timing. I have owned 12 different E36's and there is a noticable difference in power between the engines when it comes to in gear acceleration and over taking. Hope this helps Ali-bumble Scotland
